PILE WALL Filed Aug. 7, 1950 Patented Dec. 8, 1931 UNITE@ STATES ARTHRMA'UTERER, OF DORTMUND, GERMANY PILE WALL Application led August 7,1930, Serial No. 473,685, and in Germany August 7, 1929.

This invention relates to coder-dam or pile wall constructions and aimsto provide an improved method and means of correcting or compensatingfor inclination of the pile .i sections during ramming.

In the case of pile walls which are rammed in the form of boxes, andwherein the connection of the separate bars or sections of the pilewalls are located on the outside, the disadvanxo tage of having thepiles become inclined relatively to the vertical is very great, becauseit becomes inconvenient and often most diflicult in the ramming of awall to close the joints formed at the meeting points at the ends-d 13since the piles of course will not be parallelin a suitable manner andwithout considerable consunption of power. Inclination invariably occursin the ramming of the wall whether long or short and regardless of Whereit is begun, and this must be eliminated in some manner if theinclination to the vertical eX- ceeds a predetermined amount.

According to the present invention, these disadvantages are eliminatedin that intermediate portions for effecting the equalization areinserted only in one of the outer walls of the pile. These insertsconsist of two parts which are applied in the known manner (by weldingor the like) by means of a shaping iron which takes up the resistance,while the two side portions are formed with the necessary taper tocorrect the inclination. A connection of the other outer Wallis notnecesa that the equalizing portion (the so-called ramming equalization)can be produced in the simplest manner.

In the accompanying drawings is illustrated an example'of constructionaccording to the invention.

Figure 1 represents a plan view of a boxshaped pile wall constructedwith the new intermediate corrective member, and

Figure 2 is a side elevation of said member sary in this case, so thatit has the advantage looking in the direction of the arrow in Figure l.

The-applied intermediate member is shown to consist of two suitablyshaped side portions a and which are welded or otherwise joined togetheralong a central longitudinal line indicated at c. In conjunction withthis is a support d connected to the side portions c and b thereof at eby welding or other securing and which serves to stiften and rigidlysupport the two plates. The side portions or plates have suitablelocking formation or means by which they are suitably connected with theadjacent portions of the pile as shown in the illustrative example.

The described means will obviously correct or compensate for inclinationand being very simple both in form and application provides a decidedimprovement with advantages over prior expedients of the kind.

I claim 1. In a pile wall of box-shape construction, means forcorrecting or compensating for inclination of the component sectionsduring ramming into position, comprising tapered or wedge-shaped platesjoined together along a central longitudinal line and having edgesadapted to locking connection with the ends of said sections, combinedwith a reinforcing I-shaped member applied against the backs 7f, thereofalong the line of unity and joined or secured thereto along or parallelto said line; the means as a unit being inserted at intervals betweenadjacent sections of the Wall where the correction or compensation ofinclination thereof is to be eected.

2. In a pile wall of box-shape construction wherein locking connectionof the component sections is at the outer side, means for correcting orcompensating for inclination of the sections during ramming intoposition, comprising tapered or wedge-shaped plates joined along acentral longitudinal line and having edges adapted to locking connectionwith the ends of the sections, combined with a reinforcing I-shapedmember applied against the backs thereof along their line of jointureand united thereto along edges parallel to said line; said means as aunit being inserted at intervals between adjacent sections of the wallwhere correction or compenastion of inclination is necessary.

3. Inclination correction means for a pile wall according to claim l,wherein the tapered plates are connected together by welding.

4. Inclination correction means for a pile wall according to claim l,wherein the tapered plates are connected together and with thereinforcing member by welding.

In testimony whereof I alix my signature.
